      Interactions involving the T-cell receptor (TCR) and major histocompatibility complex (MHC) are fundamental to the generation of a specific immune response. The study of interpopulation differences in TCR genes may identify ...
    • T-kininogen can either induce or inhibit proliferation in Balb/c 3T3 fibroblasts, depending on the route of administration 

      Aravena, Mauricio; Pérez, C.; Pérez, V.; Acuña Castillo, Claudio; Gómez, Christian; Leiva Salcedo, Elías; Nishimura, Sumiyo; Sabaj, B.; Walter, Robin Ann (ELSEVIER SCI IRELAND LTD, 2005-03)
      T-kininogen (T-KG) is a precursor of T-kinin, the most abundant kinin in rat serum, and also acts as a strong and specific cysteine proteinase inhibitor. Its expression is strongly induced during aging in rats, and expression ...
    • T-kininogen induces endothelial cell proliferation 

      Pérez, Viviana; Leiva Salcedo, Elías; Acuña Castillo, Claudio; Aravena, Mauricio; Gómez, Christian; Sabaj Diez, Valeria; Colombo, Alicia; Nishimura, Sumiyo; Pérez Núñez, Claudio; Walter, Robin Ann; Sierra, Felipe (ELSEVIER, 2006-03)
      Basal proliferation of endothelial cells increases with age, and this might play a role in the etiology of age-related vascular diseases, as well as angiogenesis. Serum kininogen levels increase during aging in rats and ...
    • T-kininogen inhibits kinin-mediated activation of ERK in endothelial cells 

      Leiva-Salcedo, Elias; Perez, Viviana; Acuña Castillo, Claudio; Walter, Robin Ann; Sierra, Felipe (Society of Biology of Chile, 2002)
      Serum levels of T-kininogen increase dramatically as rats approach the end of their lifespan. Stable expression of the protein in Balb/c 3T3 fibroblasts leads to a dramatic inhibition of cell proliferation, as well as ...
    • T-kininogen, a cystatin-like molecule, inhibits ERK-dependent lymphocyte proliferation 

      Acuña Castillo, Claudio; Aravena, Mauricio; Leiva Salcedo, Elías; Pérez, Viviana; Gómez, Christian; Sabaj Diez, Valeria; Nishimura, Sumiyo; Pérez Núñez, Claudio; Colombo, Alicia; Walter, Robin Ann; Sierra, Felipe (ELSEVIER, 2005-12)
